Antifreeze can be very corrosive to the anode rod creating premature
failure and leave sediment in the tank. If the plumbing system is not
equipped with a bypass kit, and you intend to winterize by adding
antifreeze to the system, remove the anode rod (storing it for the winter)
and replace it with a 3/4 inch drain plug.
REFRIGERATOR
OPEN RANGE recreational vehicles use numerous different size and
model numbers of refrigerators operating on 120- volt AC. Performance
of refrigerators depends on various factors, such as, energy, venting,
leveling, humidity and atmospheric heat temperatures, but not limited to
these. All refrigerators are designed with absorption type of cooling units
requiring careful leveling and venting conditions.
Leveling
For correct operation, the refrigerator must be within three degrees of
level in any direction. Continued operation outside of these limits will
result in irreparable damage to the cooling unit in the refrigerator.
Venting
For an absorption unit to operate fully it must have two vents. One vent is
on the roof or sidewall at the upper end of the refrigerator, and a second
vent is a lower service vent and door at the lower area of the refrigerator.
A vent installed on a roof must have a screen in place to avoid birds from
entering and causing problems.
Units with two-side vents as in slide-outs, require a 12V fan to be in
operation. When upper cooling fins reach 150° Fahrenheit, the fan will
automatically start to operate. The positive wire has a five amp in line fuse
installed. Access to the fuse is inside of the lower service vent door.
Battery Drain Information
To control operating functions on several models of refrigerators, a 12-volt
DC power source, battery and/or converter are required. For gas operation
.5 amp is required through the power supply to keep the solenoid open to
supply propane gas to the burner as needed to continue to cool.
Models with a moisture reduction heater (humidity dryer) require an
additional .24 amp. This totals less than 1 amp. The drain at .74 amp is
low. However, after three to four days of continuous draw your battery will
be down, closing the solenoid and shutting down cooling capability, when
the battery drops to 11.5 volts DC.
